Use the Python built-in package pathlib

The interactive mode is written here, and you can also customize the path parameters and pass them in

# Get all xlsx, txt and other files in the specified directory. See the specific requirements
def get_file ( patterns , path ):
    all_files =[]
    p = Path ( path )
    for item in patterns :
        file_name = p.rglob ( f ' **/*.{item} ' )
        all_files.extend ( file_name ) _ _
    return all_files
 
path = input ( '>>>>Please output the path of the file:' ) # You can customize the path    
need_file = get_file ([ 'xlsx' , 'txt' ], path )  
for i in need_file :
    print ( i )
